To all whom, it may concern:

Be it known that I,WILFRIED SALMON, a citizen of the United States,residing at Brainerd, in the county of Crow Wing and State of Minnesota,have invented certain new and useful Improvements in Attachments forMilling Machines; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My invention relates to attachments for milling-machines, and has forits object to provide an attachment by means of which links and camworkcan be easily, speedily, and accurately milled.

With this object in View my invention consists in the novel constructionand arrangement of parts of my milling-machine attachment.

My invention consists particularly in the combination of parts, whichwill be first fully described and afterward specifically pointed out inthe appended claims.

Referring to the accompanying drawings, Figure 1 shows my attachment inposition for milling link and all camwork. Fig. 2 is a front elevationof the same. Fig. 3 is a top plan view of the same. Fig. 4 is aperspective view of one of the work-holding angleplates, and Fig. 5 is aperspective view of companion work-holding angle-plate.

Like numerals of reference indicate the same parts throughout theseveral drawings, in whichl is the adjustable cutter extension which issecurely fastened upon the upper arbor 2 of a milling-machine andadjustable thereon, said extension being clamped around the arbor 2, asshown. Carried by said adjustablecutter extension 1 is the arbor 3, heldin position by the adjustable centers 4 and 5. The millingcutter 6 iscarried on said arbor 3, and a pulley 7 is also secured to said arborand is belted to a pulley 8, from whence power is transmitted to thecutter.

9 indicates the bed-plate, which is provided with a series of grooves1O, 11, and 12, the central groove 11 being provided for the angle-plate13 should occasion require or the character of the work demand. Theworkholding angle-plate 13 is provided with a transverse tongue 14,which enters said groove 12,

as shown in Fig. 1. Suitable bolts 15 are employed to hold said tongue14 within the said groove 12, as shown in Fig. 1. The work-holdingangle-plate 13 comprises a vertical wall 13, a horizontal portion 13 agroove 18 in said portion, and a small slot 18, through which slot thebolt 19 0f the smaller angleplate 16 passes. 16 also indicates awork-holding angle-plate which is provided with a longitudinal tongue17, which tongue is adapted to enter a longitudinal groove 18 in theworkholding angle-plate 13. A suitable bolt 19 is passed through saidangle-plate 16 and through the angle-plate 13 to securely hold theangleplate 16 in position on said angle-plate 13, said angle-plate 16being adjustable on said angleplate 13 by this means.

19 indicates the work to be milled, which is shown in front elevation inFig. 2, said work being secured in the work-holding angle-plates 13 bymeans of clamping-bolts 20.

21 indicates the templet holding angleplate, which is provided with atransverse tongue 22, which enters the groove 10 of the bed-plate and isheld therein by means of bolts 23, said angle-plate being slidable onthe bed-plate 9. Referring to Fig. 2, it will be seen that saidangle-plate 21 is provided with a series of vertical and parallel slots24. 25 indicates the templet, which is held in position on saidangle-plate 21 by means of the clamping-bolts 26, which are providedwith enlarged heads 26, which engage the face of the templet. Nuts 26 oneach of said bolts securely hold the head 26 of said bolts in contactwith the templet.

In the adjustable cutter extension 1 I pro vide a pin 27 extendingoutwardly and above the cutter and carrying a roller 28 thereon, adaptedto engage the under side of the templet 25, as shown in Fig. 1.

Having thus described the several parts of my invention, its operationis as follows: When it is desired to use my attachment for millinglinks, camwork, and irregular surfaces, a suitable templetas, forinstance, of the form shown in the drawingsis securely clamped inposition upon the templet-holding angle-plate 21. The work to be milledis securely clamped in the work-holding angleplates 13 and 16, and asthe cutter 6 is revolved and as the bed-plate 9 is movable the workpiece and templet pass along. The roller 28 on the pin 27 being inengagement with the under side of the templet guides the cutter and theadjustable cutter extension and causes said cutter to follow the path ofthe templet and mill the work-piece according to 'links, camwork, orirregular surfaces; but of course the number and kind of templets can beunlimited, and I do not confine myself to that particular form as shownin the drawings nor to any kind or number Whatever, as the form oftemplet shown is merely for the purpose of illustrating the constructionand operation of my invention.

Having thus described my invention, I do not wish to be understood aslimiting myself in any way to the exact construction herein setfortl1,as various slight changes might be made therein which would fallwithin the limit and scope of my invention, and I consider myselfclearly entitled to all such changes and modifications.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States,

1. The combination with a cutter of a bedplate below said cutter, anangle-plate and means for adjusting the same on said bedplate, saidangle-plate being provided with a series of slots, a templet carried onsaid angle-plate, means passing through said slots to secure saidtemplet to said angle-plate, a guiding element associated with saidcutter, and adapted to engage said templet to guide said cutter, andmeans for holding the work below saidscutter, substantially asdescribed.

2. The combination with a cutter, of a bedplate below said cutter andprovided with a series of grooves, a templet associated with saidcutter, means for holding said templet, said holding means beingconstructed so as to be adjustable in one of said grooves, a workholdingangle-plate constructed so as to be longitudinally adjustable in one ofsaid grooves, a companion work-holding angleplate transverselyadjustable on the former work holding angle plate and means for clampingthe work between said two workholding angle plates, substantially asdescribed. I

In testimony whereof I aiiix my signature in presence of two witnesses.
